Spiral Staircases
Spiral Staircases for Bangalore homes — the dimensions, hardware and detailing that decide whether it still works in year five.

Spiral Staircases, in plain specification
Written for the decision, not for the mood board.
A good spiral staircases is invisible in use — everything within reach, nothing in the way, no door fouling another. Achieving that is a matter of dimensions and hardware rather than of style, which is why the specification table below matters more than the photographs.
Spiral Staircases is engineered before it is styled. The layout, the services behind it, the hardware carrying it and the clearances around it all get resolved on a drawing long before a finish is picked. Done in that order, the finish becomes a free choice. Done in reverse, the finish becomes a compromise.
In our work this sits alongside the rest of the home rather than as an isolated decision. Spiral Staircases touches the electrical layout, the ceiling, the flooring build-up and often the civil work, so it is fixed early in the drawing set and reviewed against every other trade before production starts.

Before you commit
How to choose spiral staircases
Six checks that prevent the failures we are most often called to fix.
- Rise and going are decided by the structure, not by the finish. Get them right at the RCC stage — a stair with inconsistent risers can never be fixed with cladding.
- Check headroom at the mid-landing before anything else. Under 2.1m is a permanent daily problem.
- Choose the tread material for grip when wet, especially where the stair is near a balcony or an entrance.
- Confirm the balustrade infill and height against local code before design; a 900mm rail with 150mm gaps may look elegant and be unusable in a home with children.
- Plan the lighting into the structure. Step lights and handrail profiles need conduits cast or chased before finishing.
- For a cantilever or floating stair, get the structural design signed off. This is engineering before it is interior design.
Bangalore
Spiral Staircases in Bangalore
What the city's climate, water, housing stock and society rules mean for this specification.
Most of our work is in Bangalore, and the city sets a few conditions worth knowing before specifying spiral staircases. The climate is the kindest in India to timber and joinery — no extreme dry heat, no coastal salt — but the monsoon runs long, and humidity between June and October is what tests every edge, seal and ventilation gap in a home.
Most societies here allow work between roughly 9am and 6pm, restrict Sundays, require a service-lift booking and hold a debris deposit. That schedule is written into the programme at the start, because a plan that assumes twelve working hours a day will slip in its first week.
Traffic decides delivery windows more than distance does. Material moving to Whitefield, Sarjapur or Electronic City is scheduled outside peak hours, and large items are checked against the lift and stair turn before the order rather than on delivery day.
Dust along the metro and ORR construction corridors is a real specification input. Sealed joinery, washable finishes and casement or sliding windows with good seals pay for themselves in these pockets in the first year.
We survey in Bangalore at no charge, take our own dimensions and come back with a layout, a material direction and a line-by-line estimate.
Sizing
Spiral Staircases by home size
Sizing below is what we plan spiral staircases to in each home size. These are working dimensions from completed projects, not catalogue minimums.
| Home size | Typical scope | Planning note |
|---|---|---|
| 1 BHK | Compact, single run | Compact planning, one clear gesture |
| 2 BHK | Standard, two runs | Standard scope, most common brief |
| 3 BHK | Full specification | Full scope with storage planned in litres |
| 4 BHK | Extended with island or dresser | Extended scope, bespoke elements |
| 4+ BHK / Villa | Bespoke, villa scale | Villa scale, bespoke throughout |
Cost
What moves the price of spiral staircases
We quote line by line rather than per square foot, because these are the items that actually differ between two estimates.
- Structure: an RCC stair clad in stone and a steel cantilever stair are different orders of cost.
- Tread material and edge work.
- Balustrade type, with frameless glass and brass channels at the top.
- Integrated lighting.
- Engineering and site access for heavy elements.
Process
How the work runs
Five stages, with the decisions each one locks.
We measure the space ourselves rather than working from the builder's drawing, note the services, water quality, daylight and society rules, and write down how the room is actually used. Spiral Staircases is specified against that survey, not against a catalogue.
Plans, elevations and details, with the specification written as grades and dimensions. You approve an elevation, not a render — this is the stage where changes cost nothing.
Material, finish, hardware and services are locked, and the estimate becomes a line-by-line document. We tell you exactly what this date locks and what can still change afterwards.
Factory production runs to the approved drawing while site work is prepared. Material is checked against the approved sample on arrival, in daylight, and stored correctly until the programme calls for it.
Installation, testing, snagging and a documentation file with drawings, warranties, decor codes and hardware models. A first-year service visit is scheduled at handover.
Living with it
Maintaining spiral staircases
The honest routine, and the mistakes that cost the most to undo.
Care and maintenance
- Check glass balustrade fixings annually.
- Re-seal stone treads on the same schedule as the floors, more often at the entrance.
- Keep nosings clean; grit at the nosing wears the edge fastest and is the first place a stone stair looks tired.
- Tighten handrail brackets once in the first year.
What goes wrong
- Inconsistent riser heights, which trip people and cannot be corrected later.
- Polished stone on an entrance stair that gets wet in the monsoon.
- Balustrade gaps that fail child-safety spacing.
- Deciding on a floating stair after the RCC is cast.
Detailing
Spiral Staircases detailing notes
The small decisions that separate built work from assembled work.
A 5mm shadow gap between tread and riser makes a heavy stone stair look lighter, and hides the tolerance between two site-cut pieces.
Continue the handrail past the top and bottom riser by 300mm. It is a code habit and it also reads as considered.
Where treads are book-matched or vein-continuous, the slabs must be sequenced from a single block.
Light the treads, not the well. A bright pendant in a stairwell leaves the treads in shadow, which is exactly backwards.
Questions
Spiral Staircases — answered
What rise and going should a home staircase use?
Around 160–170mm rise with a 280–320mm going for comfortable domestic use, kept identical on every step. Consistency matters more than the exact figure.
Can an existing staircase be re-clad?
Yes, if the structure is sound and the rise stays consistent after the new finish is added. The added thickness at the top and bottom step is the detail that has to be resolved first.
Is a glass balustrade safe?
Toughened laminated glass of the right thickness, properly fixed, is safe and is standard practice. The specification is about the fixing and the glass build-up, not the appearance.
How is a floating staircase supported?
By a concealed steel stringer or cantilever anchors cast into a structural wall. It is a structural decision taken with the engineer before any finish is chosen.
What is the best tread material?
Stone for durability and a continuous look with the floor; timber for warmth and quieter use. Both need a finish that is not slippery when wet.
How long does a staircase take?
Two to four weeks for cladding and balustrade once the structure is ready, with glass and metalwork measured after the treads are set.
Do you work on spiral staircases projects across Bangalore?
Yes — Bangalore is where most of our projects are, from apartments along Sarjapur Road, Whitefield and Hebbal to independent homes in Jayanagar, Indiranagar and Malleshwaram. We survey the space ourselves, work within the society's access and working-hour rules, and hand over with a documentation file. There is a dedicated page for our work in the city if you want the full picture.
Does Bangalore's climate or water affect this choice?
The climate helps and the water does not. Mild year-round temperatures are kinder to timber and joinery than almost any other Indian city, so craft detailing lasts. Hard borewell water in the eastern and northern corridors is the real constraint — it scales glass, chrome and stone, and it changes what we specify and what maintenance we ask the family to commit to.
